Im sure they told the engineers to design an amp that makes popping noises
So true, this is the usual response from such companies and the 'quirkiness' is much loved by enthusiasts. (Though to be fair a small thump on switch on is of no consequence.)
Reminds me of the Naim Armageddon power supply for the LP12. Connections apart, it looked exactly like a (olive series) Hi-cap, except that when switched on the Naim logo did not light up green in the usual manner.
The Naim rep informed us, with a perfectly straight face that this was a decision made on sound quality grounds. It was only later when I opened one up for some reason that I could see that the device was more or less an isolating transformer in a box. Unlike a Hi-cap, or any other Naim component the Armageddon was purely a/c, no rectification required so therefore no d/c available to drive the NADI board, which provides the illumonation.
This is perfectly logical and sensible but the pretence of audiophile 'integrity' had to be maintained, hence the classic 'it sounds better this way'.
To address the OPs issue, I suggest that the bass driver is observed during switch on. If there is substantial movement, you have transient d/c on the output, this could be an issue. As I said, a small thump and gentle wobble of the bass cone is not important.
